Comparative antifungal activities of processed and market Aloe vera gel

During present study, in vitro antifungal potential of three types of Aloe vera gel i.e. locally available, imported and finally processed gel that was substantially free of phenols and anthraquinones was checked against three pathogenic Aspergillus species namely A. niger, A. parasiticus and A. flavus. Growth test results of test fungi in term of dry biomass production revealed that local and imported gels have antifungal properties that become significant as the concentration of gel was increased from 5-20%. By contrast, processed gel failed to reduce the growth even at the highest concentration. Therefore, it is assumed that processed gel is least toxic as compared to local and imported A. vera gels and recommended its use for oral or medicinal purposes.
